9.Edit the new vfstab file to properly mount the new partitions during boot. In this case, each reference to c0t0d0s0 is changed to c3t130d0s0. For example:

vi/mnt/etc/vfstab

10.Shutdown the system. Type the following:

/sbin/init 0

11. Boot from the newly created boot disk. For example:

boot /sbus@1f,0/QLGC,qla@1,30000/sd@82,0

NOTE: The target device ID (sd@82) is in hexadecimal. The decimal value is used in step 3.
